NSF-funded Telescopes in Antarctica and Chile Discover Bursts of Star Formation in the Early Universe

Artist's impression of one of the South Pole Telescope-discovered sources based on observation by ALMA and Hubble Space Telescope (HST). The massive central galaxy (in blue, seen by HST) bends the light of a more distant, submillimeter-bright galaxy, forming a ring-like image of the background galaxy which is observed by ALMA (red).
